7.0 The number of research articles in a prominent journal that were written by researchers in Europe can be modeled by $P(t) = \frac{7.0}{1 + 5.4(1.2)^{-t/2}}$, where $t$ is time in years. The graphs of $P$, $P'$, and $P''$ are shown here. Graph of P Graph of P' 0.20 0.15 0.10 0.05 0.00 0 10 20 30 40 Graph of P'' 0.010 0.005 0.000 -0.005 -0.010 0 10 20 30 40 Determine to the nearest whole number the values of $t$ for which the graph of $P$ is concave up and where it is concave down, and locate any points of inflection. concave up concave down point of inflection $t = $ What does the point of inflection tell you about science articles? From the graph of $P'$ we see that $P$ has a maximum at around $t = $ meaning that the number of articles written by researchers in Europe was increasing most rapidly at around $t = $

Question 3 Superheated steam enters a turbine at 10 MPa and 780K at mass flow rate of 38.7 kg/s. The steam exits the turbine at a quality of 0.88 at 320K. Find the shaft power output (in MW) under steady- state operations (only enter the magnitude of the shaft power output). Turbine is perfectly insulated and changes in kinetic and potential energies are neglected. K = C + 273.15. Conservation of energy; \frac{dE_{cv}}{dt} = -Q_{cv} - W_{cv} + \sum_{i} \dot{m}_{i}h_{i} - \sum_{e} \dot{m}_{e}h_{e} \dot{m} = 38.7 \text{ kg/s} Q_{cv} = 0 W_{turb} = ?

Problem 3- A 50-kg copper block initially at 140°C is dropped into an insulated tank that contains 90 L of water at 10°C. Determine the final equilibrium temperature (similar to example 3 in Chapter 4) and the total entropy change (sum of entropy change of copper and water) for this process. Consider room temperature, 25°C, when finding the properties.
